Engine RPM for Backhoe

[Glrret]

I have a 2555 Shuttle and a 75B Backhoe, I've read the operator manuals and I'm not able find the recommended RPM to use.

I think backhoes are more operator preference as far as RPM.
Run whatever RPM the backhoe speed and control is where you like it.

I run my 3pt mounted backhoe with tractor throttle at 1800-2000, unless I am doing something that requires more power. It is easier for me to control it.

I think you may find in your operators manual to not run any operations below 1500 rpm, which is right about where my backhoe is plenty fast and powerful enough.

My 3-point backhoe (photo in sig) was specified for this tractor but even so, I've read that any 3-point hoe beats up the tractor more than a frame-mount version.

1350 engine rpm just sounds right for full backhoe power with smooth motions. My most common task is digging out stumps where I don't want to snap off lateral roots before I dig outward along them to free them so faster isn't necessarily better. I need to feel when the bucket encounters resistance.

If I know I can work fast and not run into obstacles then up to 1800 rpm but that's not common - and that requires more concentration to feather the end of the boom swing. Previous owner of this hoe said he tried using it a few hours and 'couldn't get the hang of it' so he never used it again. Where the roller chain for swing attaches to the chassis I found a fresh weld. I think he broke it the first time he used it. Several years now for me and no problems.

I occasionally shift the pto to its '1000 rpm output' gear, then run the engine around 1050 for very light work such as using the hoe to rip out blackberry jungle. This is essentially idling the engine, not working it. Actual rpm out the pto is still below 540 and the hoe has a decal specifying 'not over 650 rpm input' or something like that - faster than I would ever use.

Just choose what feels right. You don't need the engine's full rated pto rpm.

Every tractor/hoe is going to run best at different speeds, depending on pump and hyd cylinder sizes. You need to run it at whatever feels right for you. I run mine between 1500-1800rpms.

Without knowing any better I've been running the engine @1500 rpm it seems to operate smoothly at that setting. I found it odd that the manual didn't provide any guidance.

The tractor will tell you when it needs more....

Throttle UP!! You have the model tractor that Mahindra is having issues with. EGR,MIL light. poor heat. High RPM at this point is there only solution.:thumbsup:

 

[Glrret]

Seems like a lot of unnecessary stress on the engine and hydraulics to over come a problem in design. I hope Mahindra finds a fix soon..

I run mine on max RPM unless I'm digging out a septic tank lid. Then I'll idle down so it's really slow. When first learning, run it slow but once you get the hang of the backhoe, crank it up.

I have run Case hoes, and escalators in the past, but this is where my ignorance of tractors is going to start to show, I know on a loader cranking the RPM's doesn't really increase the power that much but it does effect the speed the attachment operates, thus making it jerky. As for the backhoe does increasing the RPM increase the power in addition to the speed? The reason I ask, I run my RPM around 1200-1500 RPM and I've realized that my backhoe doesn't seem to have much power when pulling in with the boom arm, and very little power when trying to slide material to the left or right with the boom swing cylinders. But the bucket pivot and bucket arm (stick) seem to be much stronger. Will raising the RPM improve the power of the backhoe on this kind of setup.

Really though they are made to run all day at 540rpm rating like when mowing... to little throttle would put it under more stress than more throttle than needed...

Yes,proportionally. But your boom and swing will still be a little behind(power/speed)of the other functions.

Well said.:thumbsup:
